There is ongoing work towards building FMI 2 support for SUMO - especially libsumo.


The initial goal is to build a prototype which is able to load a SUMO simulation via libsumocpp, run the simulation and provide the total amount of vehicles in the simulation as a scalar variable.


The current architecture to build the functionality for a functional mockup unit (FMU) is as followed. The source code is located in the src/fmi folder.

FMI 2.0 Compliance Checking#

Compliance with FMI 2.0 is checked with FMU Compliance Checker. It can be installed after cloning according to the build instructions.

The validation can be triggered on macOS with

fmuCheck.darwin64 /PATH/TO/SUMO/FMI/sumo-fmi2.fmu 

On some macOS systems, the validation may fail with the following message: Interceptors are not working. This can be fixed with the following call:

DYLD_INSERT_LIBRARIES=/Library/Developer/CommandLineTools/usr/lib/clang/11.0.3/lib/darwin/libclang_rt.asan_osx_dynamic.dylib fmuCheck.darwin64 /PATH/TO/SUMO/FMI/sumo-fmi2.fmu
